       <STRONG>curses_version</STRONG>, <STRONG>use_extended_names</STRONG> - miscellaneous <EM>curses</EM> extensions


</PRE><H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
       <STRONG>#include</STRONG> <STRONG>&lt;curses.h&gt;</STRONG>

       <STRONG>const</STRONG> <STRONG>char</STRONG> <STRONG>*</STRONG> <STRONG>curses_version(void);</STRONG>

</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       These  <EM>ncurses</EM>  extensions to the <EM>curses</EM> library do not fit easily into
       other functional categories.


</PRE><H3><a name="h3-curses_version">curses_version</a></H3><PRE>
       <STRONG>curses_version</STRONG> returns a pointer to a string containing  the  library's
       name  and  version  number,  including  its  patch  level,  for example
       "ncurses 6.5.20240720".


</PRE><H3><a name="h3-use_extended_names">use_extended_names</a></H3><PRE>
       <STRONG>use_extended_names</STRONG> configures  whether  the  library  recognizes  user-
       defined  or  nonstandard <EM>terminfo</EM> capability names that may be compiled
       into  terminal  type  descriptions   via   the   <STRONG><A HREF="curs_terminfo.3x.html">curs_terminfo(3x)</A></STRONG>   or
       <STRONG><A HREF="curs_termcap.3x.html">curs_termcap(3x)</A></STRONG>  interfaces.   Normally  these names are available for
       use, since the essential decision is made through use  of  <STRONG><A HREF="tic.1m.html">tic(1)</A></STRONG>'s  <STRONG>-x</STRONG>
       option  to  include  such  extensions  in  terminal  type descriptions.
       <STRONG>use_extended_names</STRONG>  can  prevent   <EM>ncurses</EM>   from   recognizing   these
       capabilities  to  ensure  compatibility  with  other implementations of
       <EM>curses</EM>.


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       <STRONG>curses_version</STRONG> returns a constant string.

       <STRONG>use_extended_names</STRONG> returns the previous state  of  extended  capability
       name recognition, allowing you to save this property and restore it.


</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
       The  pointer  returned  by  <STRONG>curses_version</STRONG>  corresponds  to  statically
       allocated memory; do not attempt to <STRONG>free(3)</STRONG> it.


</PRE><H2><a name="h2-EXTENSIONS">EXTENSIONS</a></H2><PRE>
       These functions are <EM>ncurses</EM> extensions,  and  are  not  found  in  SVr4
       <EM>curses</EM>, 4.4BSD <EM>curses</EM>, or any other previous <EM>curses</EM> implementation.


</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       Applications employing <EM>ncurses</EM> extensions should condition their use on
       the visibility of the <STRONG>NCURSES_VERSION</STRONG> preprocessor macro.
